Effects of ball milling on the structure of cotton
Jan 17, 2019· It breaks down the fibrous structures, exposes more surface area, and opens the pores of cotton. The initial decrease in pore size may have resulted from impact compression by the ball mill without the damage and fragmentation that occur at longer ball-milling times. The samples were studied by TGA and DTG under an N 2 atmosphere. All data were
A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill. In addition, the agglomerated particles are mixed into the coarse powder in the separator and recirculated through the mill.
